ALEXANDER S'IBOBL, OF NEW YORK, N. Y., ASSIGNOR TO S. STERNAU & COMPANY, INC., A CORPORATION OF NEW YORK.

SOLID ALCOHOL AND PROCESS OF PRODUCING SAME.

No Drawing.

To all whom it may concern Be it known that I, ALEXANDER SmonL, a subject of the King of Hungary, and a resident of the borough of Manhattan, city,

' the mixture into a solid mass.

county, and State of New York, have in-- vented a certain new and useful SOlld Alcohol and Process of Producing Same, of which the following is a specification.

This invention relates to improvements n solidified or solid alcohol, intended primarily for burning in portable stoves or cans.

The object of the invention is to produce a solid alcohol which can be burned in a can and the solid residuum of which, after the alcohol is entirely consumed, will occupy but a thin layer in the bottom of the can.

One way of carrying out my process 1s to take 100parts of alcohol and mix with the same 2 or 3 parts of a suitable fatty acld, such as stearic acid. To this is added a solution of caustic soda or sodium hydrate so as to saponify the fatty acid and convert The amount of caustic soda added should be not suflicient to neutralize all of the stearic acid, but on the contrary a small amount should be left free.

When the mass in a can or stove is ignited the alcohol burns leaving behind the saponified mass. .After all the alcohol is burned, the free stearic acid will melt and form with the sodium stearate but a thin layer in the bottom of the can, whereas if no free stearic acid is present, the residue which is left behind, will form a porous, bulky mass which fills a big part 0 the can and sometimes even rises a ove the top opening;

In carrying out the process t e alcohol is first preferably heated, to say between 140 and 160 degrees Fahrenheit, so that the stearic acid will more readily dissolve in it. In order to ascertain exactly the amount of caustic soda necessary to be added to the solution, the process may be carried out by first adding the stearic acid to the alcohol and then adding sufiicient of the solution of caustic soda to produce a neutral reaction:i

then a small amount of stearic acid is adde Specification of Letters Patent.

Application filed February 11, 1915.

Patented May 14, 1918.

Serial No. 7,503.

so as to produce an acid reaction andthus leave a certain amount of free stearic acid in the mixture. After the proper proportions have been obtained for known materials, it is, of course, very convenient to add all of the stearic acid to the alcohol at one time and .then. caustic soda insufiicient to entirely neutralize the mixture, leaving an excess of unneutralized stearic acid.

Having now described my invention, what I claim as new and desire to secure by Letters Patent, is:

1. The process of producing solid alcohol, which consists in addingto the alcohol a small amount of stearic acid and dissolving the same therein, then adding suflicient of a solution of caustic soda to produce a neutral reaction, then adding a small amount of stearic acid to produce an acid reaction and leave a certain amount of free stearic acid in the mass.

2. The process of producing solid alcohol which consists in heati alcohol to a temperature of between 140 and 160 degrees Fahrenheit, adding to 100 parts of the heated alcohol two or three parts of stearic acid, addin caustic soda sufiicient to neutralize neafiy all of the stearic acid, and allowing the mixtureto cool.

3. A new article of manufacture which consists of alcohol, sodium stearate and stearic acid;

4. A new article of manufacture which consists of alcohol, sodium stearate and a fatty acid.

5. A new article of manufacture which consists of alcohol, sodium stearate and a fusible fatty acid.

A new article of manufacture which consists of alcohol, soap and a fatty acid.

7. A new article 0 manufacture which consists of alcohol, metallic soap and a fatty ac1 This specification signed. and witnessed this 30 day of Jan., 1915. A
